If you asked me 15 hours ago to rate thios game, I would have given 5 stars without a moments hesitation. Because the many campaing is simply great. So what happened? After finishing (most of) the maion campaing the game forces you to finish most of the side missions before yopu get to see the ending. And man: those are some of the worst and most annoying things I've done in any game. Because it makes you do the same things over and over again.
An example? Twoface is robbing a bank: Go in, beat up thze bad guys, Two Face access the security system, you get locked in, beat up more bad guys. Great whats next? Oh, Two Face is robbing a similar looking bank. Go in, beat up thze bad guys, Two Face access the security system, you get locked in, beat up more bad guys. Great whats next?Oh, Two Face is robbing a third bank that looks almost like the first two. Gee, I wonder what will happen next?!?
And this is one of the more fun missions. Catch Penguin? Need to tag a mini van, follow it to a weapons hideout, beat up the guys, detonate a vault. Good work! Now follow a second mini van, beat up the guys,... You get the point.
And want to feel really dead inside? Why don't you search and rescue thos 15 fire figters? Still having fun? Here are 40+ roadblocks, 20+ watch towers and 20+ mines to search and clean up (every one with multiple similar enemies you've to fight.
I ended up using a god mode cheat - and still needed more than 15 hours of repetive, teadious work to get to the point where they would finally show me the ending. So my advise to you: Don't bother - just watch a youtube video.
